This Master's Thesis by the title of "Contribution of established and alternative desalination technologies as approach to the international water crisis" deals with the circumstances of the global water scarcity - which doubtlessly can be called a global water crisis, which is affecting various regions of our world and over a billion of people - and desalination as a potential solution, or part of the overall solution, to this growing problem. The background of the world's water is discussed, explaining basic chemical and physical coherences, reviewing the hydrological cycle and showing geographical concerns of its distribution, extraction and consumption, also including the interdependencies of population and water for food production, drinking water use (including hygienic usage) and water for drinking only. Different applications of membrane processes and thermal desalination methods are presented and the potential for certain processes by means of technological improvements and the combination with renewable energy sources is presented. The excessive use of fossil fuels in general, and for the power supply for desalination plants in this very example does cause significant harm to the environment and accelerates climate change. This is why there is a significant need to employ renewable energy resources to operate desalination plants in a sustainable manner. Attempts to solve the scarce water situation based exclusively on technology, such as desalination of saline water, will only have a limited impact, due to their environmental considerations and costs. There are certain areas that must be improved on, forming a well balanced mix of water management, including an improvement in the efficiency of water usage, particularly for irrigation, refurbishment of drinking water production and distribution resources, protection of reserves and better pollution control. It remains to be seen how much commitment from the world's leaders will be brought up to place certain pieces in the water management puzzle at the right position, in order to solve the looming water crisis...
